UA842: SYD → LAX – Flight Guide

The Boeing 787-9 is a long-range, wide-body twin-engine jet and the stretched version of the 787-8. It entered service in 2014 and is known for its composite materials construction, fuel efficiency, and passenger-friendly cabin features including large windows, higher cabin humidity, and lower cabin altitude pressure which reduces jet lag and passenger fatigue.

The Boeing 787-9 has an excellent safety record. Despite early teething issues with lithium-ion batteries in 2013 (resolved with redesigned systems), the 787 family has proven to be highly reliable. It is operated by dozens of major airlines on long-haul routes worldwide and meets all current international airworthiness standards.

Typically 250-296 passengers in a two-class configuration. In a three-class layout with business and premium economy, around 250 seats. Some high-density single-class configurations go up to 335 seats. The standard widebody 2-4-2 or 3-3-3 economy layout varies by airline.

The 787 cabin is pressurised to the equivalent of 6,000 feet altitude (vs 8,000 on older jets), which means passengers arrive feeling less fatigued. Cabin humidity is significantly higher (15-20% vs 5-10% on older aircraft), reducing the dryness that causes headaches and dry eyes. Windows are 30% larger and use electrochromic dimming instead of plastic shades.

In economy, rows 20-30 over the wing are the smoothest. Bulkhead rows offer extra legroom but have fixed armrests. Avoid seats next to the rear galley or toilets. In business class, direct aisle access seats are the most desirable — check your airline's specific configuration as layouts vary widely.

The 787-9 is one of the quietest commercial jets flying today. The GEnx or Trent 1000 engines have advanced noise-reducing technology, and the composite fuselage absorbs vibration more effectively than aluminium. Passengers frequently comment on how quiet the cabin is even at cruise.

Major operators include United Airlines, American Airlines, British Airways, Air New Zealand, Qantas, Japan Airlines, ANA, Emirates, Etihad, Singapore Airlines, Virgin Atlantic, and many others. It is one of the most popular long-haul jets in the world.

The 787-9 has a range of approximately 14,140 km (8,786 miles), enabling ultra-long-haul routes such as Perth to London, New York to Singapore, and many other point-to-point connections that previously required a fuel stop.

Most airlines operating the 787-9 on long-haul routes offer Wi-Fi connectivity. The speed and cost vary by airline and service provider. Satellite-based systems are standard, with some airlines offering free messaging and paid browsing tiers.

Yes, the 787-9 is an excellent choice for nervous flyers. The fly-by-wire system actively dampens turbulence, the engines are very quiet and smooth, and the larger windows give better situational awareness. The lower cabin altitude also reduces the anxiety that some passengers associate with altitude-related discomfort.

The 787 uses an electric bleed-free air system that draws fresh outside air through powerful compressors rather than the engine bleed system used by older jets. This means cleaner, fresher cabin air that is less prone to contamination. Combined with higher humidity, the air quality is widely regarded as the best of any commercial aircraft.

The 787-9 typically has 6-8 toilets depending on configuration. Long-haul configurations ensure adequate facilities for the passenger count. Queue times are generally reasonable on well-configured aircraft, with toilets distributed between forward, mid-cabin, and rear locations.

The 787-9 is widely considered the most passenger-friendly aircraft for very long flights. The lower cabin altitude, higher humidity, larger windows, quieter engines, and smoother ride all contribute to arriving less exhausted than on older long-haul jets. Business class configurations on most major carriers are excellent.

The most common economy layout on the 787-9 is 3-3-3 (nine across), which is one seat wider than on older widebody jets per row. Some airlines use a 2-4-2 configuration for more premium economy product. The cabin width of 5.49m allows reasonable seat widths even in the densest configurations.

Both are modern, fuel-efficient widebody jets with excellent passenger comfort. The A350 has a slightly wider cabin and uses a different composite construction approach. The 787 is more widely operated globally and has a larger installed base. Passengers generally report similarly high comfort levels on both aircraft — the airline's specific product often matters more than the aircraft type.
